Sensor mounting method for pile foundation detection
The invention discloses a sensor mounting method for pile foundation detection. The sensor mounting method comprises the following steps: determining a first drilling position on a test pile according to the pile diameter of the test pile under the condition that the pile sinking of the test pile reaches a preset elevation value; determining a second drilling position on the test pile according to a preset hole center distance; drilling a first mounting hole and a second mounting hole in the test pile according to the first drilling position and the second drilling position; and respectively mounting a strain force sensor and an acceleration sensor on the first mounting hole and the second mounting hole through threaded fasteners. According to the sensor mounting method, the strain force sensor and the acceleration sensor are mounted by drilling holes and adopting the threaded fasteners, the fixing mode is firm and reliable, signal stability is ensured, a complete waveform curve can be obtained, steel pipe pile mounting is not needed, sensor damage caused by large hammering energy is avoided, the drilling position is determined according to the pile diameter of the test pile, so that the drilling position can be quickly determined, and the detection requirement is met.
本发明公开了一种用于桩基检测的传感器安装方法，包括在试验桩沉桩达到预设的标高值的情况下，根据试验桩的桩径在试验桩上确定第一钻孔位置；根据预设的孔中心距在试验桩上确定第二钻孔位置；根据第一钻孔位置和第二钻孔位置，在试验桩上钻出第一安装孔和第二安装孔；通过螺纹紧固件分别在第一安装孔和第二安装孔上安装应变力传感器和加速度传感器。本发明实施例通过钻孔和采用螺纹紧固件的方式安装应变力传感器和加速度传感器，固定方式牢固可靠，确保信号稳定，有利于获得完整的波形曲线，且无需采用钢管桩安装，避免因锤击能量较大而导致传感器损坏，根据试验桩的桩径确定钻孔位置，有利于快速确定钻孔位置以及满足检测要求。
